I usually select cuttings from stems with blooms that have recently pasted their prime, a little bit earlier than I would otherwise dead head the spent blooms. The absolute optimal time is after the bud shows color, before it opens, but few roses are so difficult to root (with good technique) that you really need to sacrifice the bloom before it can be enjoyed.

Where do I find "good technique" to root roses?
Thanks - Jim

Jim, you find "good technique" through research and experimentation. Most people start with someone else's proven, but not exhaustively explained method and then have to tweak it and ask questions to fill in the details and fit local conditions. Few manage a high success rate on the first try.

Thanks for the input, Rosyone.

Jim--I found a section entitled "How to Take Cuttings" in th Antique Rose Emporium catalog. It has several methods from which to choose, all of them, deceptively I'll bet, easy to do! I will experiment and then post with the results. Good luck!
